The E169 USB Dongle is a vast improvement on the entry level devices, such as the E156, E160 and the older E220. However the E169 does not and will never support HSUPA (for higher upload speeds and lower latency) - sported by higher spec devices such as the E170 and the Option Icon 431. If you're looking to purchase a mobile broadband modem investigate the price of these higher specification devices first - the difference may be minimal and well worth the upgrade.
